Honestly, it was OK. We did not have a lot growing up and so I had scrounged this and that often building things custom to take advantage of the room and passive acoustics to get good sound.
I, and friends and family, listened to a lot of music on it.
Then I did something one day that would turn out to be special!
Just for kicks, I wondered whether recording using the same speakers that would play the recording back would sound good.
Turns out yes! It was a little like a hologram. If you played those recordings in my room, you would hear the house! Mom cooking in the kitchen, living room TV, complete with CRT wine, in the living room, people talking...
It was all there! And one could place the sounds as if they were really happening. Listening in, say the middle of the night, was dramatic. With eyes closed, it was like midday. Hard to tell otherwise.
And those recordings only worked on that system, in that room.
Today, I bet software would tease out what I did on a wider range of listening scenarios. But back then, some considered it magic, and only in that room.
So when I left home, I left it all and some tapes and encouraged anyone wanting to hear family life from some years ago to go and listen before it all gets torn apart.
My mom sold the house and that was the end of an era. Sadly, the tapes have been lost too.
All I know is you can use a capable preamp to record through your speakers and when that recording is played on that system, it will be magic!
